Our patented Ultra-Strap is used in our 20, 30 \u0026amp; 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.\u003c\/p\u003e \u003cp\u003eBecket ?
